Dear Anshu,
1) You are missing N2 in param:

( for(I,1,N), param(X,N) do



    X[I]#> 0,

    X[I+1]#> X[I],

    X[N]#< N2

 ),
2) I think you should add N to second param. The same with next set of
loops.

 ( for(I,1,N),param(X,N) do

   (for(J,I,N),param(X,I) do

    (for(K,J+1,N),param(X,J) do
I hope that helps

Best regards
